Keys

.LR a

and 

.LR j

.LR s

and 

.LR k

rotate left,

.LR d

and 

.LR l

.LR f

and 

.LR ;

.LR z ,

.LR p

Generate an official-looking but utterly nonsensical bureaucratic report as

.L "pic | eqn | tbl | troff -mm"

input.

Options

.BR -p ,

.B -e

and

.B -t

add gibberish diagrams, equations and tables.

.TP

.B juggle

Display the juggling

.I pattern

using the optional initial

.I start

pattern.

The number of hands involved (default 2) can be specified with

.BR -h ,

and

.I delay

can be used to speed up or slow down the action (default is 20).

Try the pattern 333333441333333 or 333353505151512333333

or YWUSQOMKIGECA

(see

.BR http://seehuhn.de/jong/theory.html ).

.TP

.B life

Play the game of Life, given an initial position.

There is a library of interesting initial positions;

the library is consulted if

.I startfile

cannot be found.

.TP

.B mahjongg

Remove all tiles

from the board. Click on tiles with the same face that

are not blocked by others. A blocked tile is one that is partially or

fully covered on top or has neighbouring tiles to the left and right.

The game finishes when either all tiles are gone or there are no

more moves left. The arguments are for changing background

.RB (-b),

tile

.RB (-t)

and layout

.RB (-l)

images;

.RB -c

selects a true-color buffer image, for use with

drawterm or in case selecting a tile obscures it completely;

.RB -f

causes mahjongg to indicate non-blocked tiles on mouse-over.

The 

.LR N

key will generate a new level, 

.LR R

restarts the current one. 

.LR Q

and 

.LR Del

quit, 

.LR H

gives a hint, either trying to match the currently selected tile, or if no tile is

selected finding out the first available tile.

.LR U

and

.LR Bksp

undo the last move,

.LR C

tries to solve the level.

.TP

.B memo

Remove all tiles from the board.

At first, pictures of various Bell Labs employees, Lucent Technologies' logo, and Glenda will appear.

Memorize the sequence, then click to hide them and begin.

Use the mouse to select two tiles.

If they are the same, the tiles will disappear, otherwise the tiles will flip back and you will get a chance to try again.

Button 3 generates a memu allowing you to restart, switch between easy and hard modes, and exit.

The

.B -h

option sets the game to hard mode.

Once the game has been completed, a message pops up with how long it took to win.

Use the button 3 menu to choose a mode, or click to play again.

.TP

.B sokoban

Guide Glenda through a room full of walls, pebbles and holes to put

the pebbles in.  Your goal is to arrange all pebbles into holes by

pushing them around, but you can only push a pebble if there is no

wall or another pebble blocking the way.

Arrow keys move Glenda up-down-left-right.  

.LR N 

and 

.LR P 

keys switch between

the next and previous levels, 

.LR R

restarts the current level.  

.LR Del 

and

.LR Q

quit.  Button 3 invokes a menu to restart the current level, load different level sets, and en- and disable animation of multi-step moves.

Button 2 lets you change between levels. 

Button 1 lets you do multi-step moves and pushes,

by clicking it on the destination where you want Glenda to go.

Glenda will only move if it can reach the destination.

For a multi-step push the pebble must be next to Glenda,

the destination must be on the same row or column,

and there must be a free place next to the destination

where the pebble can be pushed to.

Otherwise, if possible, Glenda will walk to the destination without pushing the pebble.

.I Sokoban

accepts a level file as its argument.

.TP

.B sudoku

.I Sudoku

is a puzzle game from Japan.  The goal of the game is to

fill the numbers 1 to 9 in all squares of the 9x9 board following a

few simple rules: no digit should repeat on the same row and column,

and no digit should repeat in the same 3x3 boxes outlined with thicker

lines.  The board is initially filled with a partial solution which

can be used for inferring digits for the empty squares.  The top row

of the board contains the digits 1 through 9, clicking on one of those

digits selects that number for placement on the board, clicking it

again will deselect that digit.  Clicking on an empty square will then

affix the square with the selected digit or, if no digit is selected

empty the square.

.SH BUGS

In

.I 4s

and

.IR 5s ,

mouse warping (when the game is resumed,

and when a new tile appears) does not happen when

the mouse cursor is outside the game window.

Those who prefer to use the keyboard without the mouse

cursor blocking the view (or being warped all the time)

may consider this a feature.
